Mukesh borrowed a sum of Rs. 10000 at simple interest from a bank. After two years he takes Rs. 12000 more as loan and discharge all the debt at the end of next 3 years depositing Rs. 27160 to the bank. What is the rate of interest per annum?
(a) 5%
(b) 6%
(c) 8%
(d) 10%
(e) None of these

• si=27160-(principal amount)=27160-22000=5160.
  now,(10000*5*R/100) + (12000*3*R/100)=5160.
  500R+360R=5160.....Rate=6%.

• ans is b
  interest charges on 10000 for 5 yeras and charges on 12000 for 3 years
  let the rate of interest be x per annum
  10000+5(x/100 * 10000)+12000+3(x/100*12000)=27160
  on solving we get x=6
